Hi guys,
I can't seem to get a stable 4G connection on my Epic 4G for some reason. When I toggle the "4G" to "ON", it would connect for a split second and immediately Disconnects and tries to connect again and again. My friend tested his phone (Nexus S 4G) and he connects just fine with data speed of 3,000kbps on Speedtest compared to my miserable 600-700kbps. I've also tried testing this in several different areas including major cities that supposedly cover "4G" and it does the same
I'm currently running SRF 1.2 ROM on Genocide 2.0 Kernel but I believe this issue was present even before rooting my phone. I also tried using different modems (EB13, EC05, EE03, EF02, EG22, EH17) but it made almost no difference to my 4G connection.
Does anyone have any suggestion on this??? I would really like to experience my 4G connection on my supposed 4G phone.
I have the same set up as you, and the same spotty 4g. Sometimes it's very hard to keep a stable 4g connection even in areas where I know 4g has been strong. It disconnects, or it pretends that it is connected but data really isn't going through.
Though, 4g is kinda new to my area and there are rumors that it's still in testing phases. Also, I don't have any input from other 4g users here. So in the end I'm not sure if its just my epic, or if there are wider issues.

Strong 4g signal
I am also running SFR 1.2 and I get very strong/stable 4g speeds. I live in Chicago (Sprint 4g has been here for a while), and I get 3-4Mbps in my apartment on 4g. This is enough to do things like play Xbox Live or Skype using my 4g. I have noticed that while traveling on trains in the area the connection tends to go on and off, but I would say that overall, I usually have a great connection.
This may just be in your area, where are you located?

I have the same issues, even though the Sprint coverage map shows I should be able to get 4G inside my house.
After researching, what I have found is you must find the nearest Sprint tower that has 4G, hold your left hand directly on the control board of the tower, and while placing your right big toe directly on the battery of your phone (must be the right big toe, the left big toe will not carry current correctly), you must complete the following key sequence on the dialer (###WTF***4G###***). Only then will you receive a 4G signal. Now be aware this will only enable the signal to last for 15 seconds. If you need more time that that, you must repeat the process. Oh...and By the way...This will only get you 1 bar of 4G service. I will be working on a detailed guide for 2 bars. There is no known method to actually get 3 bars of 4G service!!
Sorry, but this is a good of an explanation as anyone from Sprint has given me.
You may now return to your normally weak 3G Sprint signal.

Ok so I found out today that I have 4g in my area n I will turn it on and it will scan for about 30 seconds and then connect real quick then disconnect I can confirm I have 4g in my area as my friends evo connects . I already tried doing whitslacks
Start over method n same thing .

wow so noone has any insight ?
I have the exact same problem.
If I am using the 4G it stays connected, otherwise:
connected to sprint
scanning...
Obtaining IP Address
connected to sprint
More and likely its a weak signal. It was like that for my area but waited couple months later it gave me a stronger signal now. Unless your friend is picking up signal at your house and you are not. Then I have no clue. Update your prl?

i have a wimax tower right across the street (i see it outside my window)
full bars, perfect coverage
I'm having 4g trouble as well. I have full reception and am in a confirmed working 4g location. The phone keeps scanning for 4g but can't find anything.

that's a different problem if you can't connect at all.
I think I am bouncing around to multiple wimax towers.
Any idea how to fix this?
I had the same problem on PRI 1.3x when upgraded to PRI 1.4x the problem was fixed. I made the mistake of upgrading to 1.77 and now my phone connects/reconnects all the time on 4g.
Im located in best coverage area and I cant find a signal. I live in SI NY, 4G just went live the other day. Even though the map says I have signal could the signal not be lit yet? I have a rooted stock rom 2.2 evo, I know someone with an unrooted evo but they dont have 4G by their house yet, I will have them test it as soon as I can.
ok i got in contact with someone with an unrooted evo and they checked a different part of SI which the map says has coverage and he cant get a signal.
Not once (except for ookees) did anybody say if they were rooted or not, what ROM they are using, or any other information except for "I have 4G coverage, I cannot connect". Need more information.
Edit:
Also, the OP has "current phone : samsung vibrant rooted running vibrant 5" in his signature...which is on Tmobile and doesnt have 4G.

This is really frustrating. If I am in other areas, my 4G works fine.
If I keep the link "hot" by constantly using data, it wont drop the 4G connection.
Otherwise-
Connects, works for 30 seconds, disconnects, scans, reconnects with new IP, disconnects, over and over and over.
My wimax radio is NOT broken, 4G does work in most areas, but at home where I get multiple 4G towers surrounding me (downtown) I think it is tower jumping.
anyone? can anyone help with this?
download the WIMAX RSA key checker from the market and see if your RSA keys are missing, if they are i feel bad for you. (I lost mine aswell) Im still dealing with sprint to get my phone either replaced or covered by insurance (which means i have to fully unroot it and claim it as a software issure with an OverTheAir (OTA) update. They usually fall for this and replace it no charge. But if they find out or expect root, they make you pay a 100$ deductible to get a refurbished phone (rooted or not) but there is a slight chance you'll get an Evo 3D in return ^_^ I hear they're not handing out Evo 4Gs anymore
I've noticed this over the past month and thought I'd share and see if anyone has been having the same experience with 4G data.
I'm in Miami Lakes, which is a suburb of Miami, and while Miami officially has 4G now, my suburb isn't listed in Sprint's coverage map as being covered by 4G yet. However, I've been getting a 4G signal at home for over a month now.
I have noticed, though, that I can't download/received MMS messages while on 4G but as soon as I switch to 3G, they download just fine.
Another thing I noticed is, it takes a second or two for 4G data to actually wake up. What I mean is, when my phone locks (screen turns off) and I turn it back on and go into an app that needs a data connection (i.e. Facebook), about 50% of the time I'll get a message from the app saying that there is no data connection (eve though the 4G icon shows I am connected to 4G) but if I back out, give it a second, and go back in, all of the sudden everything is fine. Just like my MMS issue, that doesn't happen with 3G either.
I think it's safe to assume that these issues are due to the fact that 4G isn't officially implemented in my area yet and they are still configuring and installing these towers I'm getting signal from.
I thought it'd be interesting to see if anyone else is having these issues in their "unofficially" 4G-covered areas or even if some people with 4G officially have experienced these issues.
I should also note, I've experienced these issues with both my EVO and my Epic.
I'm pretty much sure about this as of today. Still have my SGS2 and in same areas itSGS2 was signalstrong side by side with EpicTouch when it switched to 3G. I'll then connect to 4G via my wireless MiFi and Epic kicks into a rocksolid 4G connection. OR I'll kick airplane mode in, go back and Epic will return to 4G.
So this is a bonafide issue.
Also pretty sure updates will fix this....but Sprint needs to get the word.
If this has been stated here sorry bout the repeat.
For anyone having data speed issues, I'd suggest you contact samsung to let them know or they won't know there is an issue with data on this phone.

I've had the E4GT for less than 24hrs, and biggest issue is the less than splendid cell reception. Sitting in my living room i used to get 2-3 bars- this thing constantly throws into roaming. I updated my PRL, Profile, and Firmware. Didn't know what the latest PRL was that was out.
I know this thing has only been out a few days, so i understand some bugs. Is anyone else having signal issues where they didn't before?
I'm really trying rock this for a couple days stock before i root the hell out of it, lol.
Thanks for any input. Link me to resources if you like, i have no issues reading up on my own if this is a common issue.

Ditto! I even have an Air Rave and reception is poor.
I am running into the same situation. It keeps on switching between roaming and normal for no reason. I usually get pretty good reception in my room. It will sit there at about 2-3 bars reception, few minutes later its roaming. The phone hasn't been moved at all.
This happened to me 20 minutes after I got it on Friday but after a reboot it was fine. No problem since then. I assumed it was a network issue.
Same issue here, even with Airave (evo next to SG2 has better signal)
Huh, I'm getting better reception than my Evo 4G. The Epic Touch now works in my condo elevator at basement garage level where the Evo would consistently drop a call.
has anyone did a signal strength comparison instead of bars. they may have different values per bar on different phones.
Returns are warranted?

I wonder if there is a difference in radios or something. My experience tells me that this radio is finicky as heck, and I don't know why.
Is there a way to find out if Samsung used different parts or suppliers to make the Epic Touch?
I remember HTC doing this with their phones, and some would be fine, and some would not (different issue each phone, lol)
Mine was doing the same i switched the phone to only go on sprints network and has been fine. I rarely need true roaming but it would go into roaming even when sprint service was available.
I think Sprint may be doing network upgrades/maintenance. The same phenomenon occurs on my Epic 4G Touch and multiple Nexus S 4G's. I'll see signal jump from -106 dBm to -76 dBm and in some places go into roaming. Nothing to worry about as long as it works. They may be upgrading equipment to support EVDO rev B hopefully.
I get much better 4G reception on the E4GT than the NS4G, FWIW.
My signal isn't as good as my photon was better then my evo 3d. I usually don't roam much. Trust me when I say this, reception could be worse lol ill deal with it!!

I hope the poor signal has to do with upgrading to EvDo RevB on Oct7
Thank God I am not alone. My cell reception too is finicky. In places my old evo (which my girl use now)have weak signal my epic touch would roam in and out. Sometimes it won't leave roaming even after I get to a known good reception area. Only a reboot would kick it back to sprint network. I read somewhere that calling sprint and having them reset my phone on their end might help. I am going to try this out as soon as I get home.
I've noticed a network behavior I did not have on my EVO 4G. The Note 2 can't switch to 4G when it's busy using 3G. You could be standing under a 4G tower and the phone won't switch if, for instance, you're downloading a file. My EVO 4G would switch between 3G and Wimax no problem.
Is this a hardware limitation? Software problem?
Could be a difference between Wimax and LTE connections. I have never noticed this issue, but I also only saw a Wimax signal a couple of times. I had the OG Evo and then the Evo 3D, but rarely ever saw a Wimax signal. With my Evo LTE, my entire area is blanketed with LTE, so I'm never switching between 3G and LTE in the middle of a download. I'll try to test out this scenario within the next few days with both my Note 2 and my Evo LTE. If I do have any weird findings with either, I'll call Sprint and activate my black Evo LTE and see how it handles the data connection transition. That way I will have tested the specific data transition with 3 different devices, and should be able to come up with a some what conclusive decision with what's going on. If someone else has a Wimax device and is in a Wimax area, it would be nice if they could compare that side by side with their LTE device! I still have my Evo 3D, but like I said earlier, I'm not near a Wimax area for testing...

Hmmmm. Interesting. I never noticed that behaviour on my NII or EvoLTE. I still have my E4GT laying around so maybe I'll activate it and see what happens. I've been lucky in my area seeing as we had WiMax coverage even before the release of the OG Evo and are pretty well covered with LTE.

I've noticed OPs issue. The same kinda thing will happen when I am driving away from my home and my phone tries to hang on to my signal booster. Once I actually loose the connection my phone will jump onto 3G and usually by that point I have Pandora opened and trying to play. It wont switch to LTE until either the song is fully buffered (witch in this case doesn't happen because the 3G at this point sucks (connected to tower)) or I go to Airplane Mode and shut off all radios and then turn off Airplane Mode. The LTE will come right up and I have no data issues.
If I'm not near my signal booster, like at work, and I am at my desk getting LTE, when I put my phone in my pocket and walk around it will drop to 3G. When I come back to my desk and try to start using an app that requires data, it wont jump back to LTE until I either close the app that is pulling the data, or do another Airplane Mode toggle.
I think all it is, is just the scan times between searching for an LTE signal (I think like 30 seconds and not every 1 second) to save battery. I could be wrong though. It is annoying to have to go through this routine every day though.
I've never payed attention to it before but now I do see what the op is talking about. Mine won't switch either

I think it's a bit random in my experience. It's it currently downloading something, it'll stay. But I've seen it switch it though while streaming a movie/show/event. I've had the GN2 get suck where it switch towers, but wasn't really connecting, which required the airplaine mode on/off trick.
spotopolis,
You hit right on the kind of scenario I am experiencing. I'm in the car listening to a streaming podcast or streaming music. And because the car is moving, the phone sometimes switches to 3G and will not get back on to LTE unless I kill all network access. It's like the phone needs a moment to breath before attempting to connect LTE.
This would not bug me so much if 3G had a data rate better than 50kbps. When I'm stuck in 3G, forget streaming or downloading anything. Very frustrating.
Trying to figure out if this is a limit of Note 2, LTE, Sprint's LTE or a bug.
It's an LTE issue. I've experienced the same behavior with 4G when I was in NY last weekend. Soon as I stopped Pandora and 3G went idle 4G came on. And no that is not an issue with Wimax devices. Coming from an E4GT and Evo 3D covered in Wimax coverage here in Hartford CT 4G automatically connects and overrides 3G even if 3G is active. However that's an issue too because the 3G to Wimax handoff sucks which leaves your data hanging for a sec. I usually have to stop my downloads and restart them while on the new 4G connection lol

That would be a software issue, not Wimax problem. I had some apps that handled network switches very well. That includes going from cell networks (3G/4G) to WIFI. Perfect example is what I noticed using streaming music on my EVO 4G. (The follow is true for these apps many versions ago.)
1. Slacker, terrible making switch. 99% would stop playback.
2. Pandora, better than Slacker. Could pause during playback but would pickup if network regained soon.
3. Google Music, best of the bunch. Can handle network jumps very well. I think partly due to caching the next song while playing current song.
I thought i was the only one having this issue.... good to know.
I've never had this problem. My n2 has no problem switching from 3g to 4g. When I'm driving while listening to Pandora, I hit areas that only 3g and phone shows 3g. Then afterwards it goes back to 4g with no problem. It does it effortlessly and on a daily. I live in Chicago and we are lte for the most part but I know certain suburbs do not have 4g and my n2 switches without a problem. Guess I'm lucky.

Interesting thread. I'm seeking an answer too. FWIW I don't own a Note 2 but also noticed this behaviour, with my SGS3. I created a thread some time ago (http://forum.xda-developers.com/showthread.php?t=1989176) but there was little interest, which surprised me, considering how annoying it can be.
